Testimonials for Heavy Duty Oil Stabilizer

one day me and my dad (joe) were in o'reilly auto parts and saw this oil stabilizer so we bought 2 quarts b/c the pickup above always used (Burned) oil. today (3-24-08) we put it in and there was an immediate difference!!!!!!!

the engine has a scored piston beacause it got overheated and was ran on poor fuel a long time ago. so we went driving around and noticed that it ran quieter and smother no really loud rattle. it was windy and we were driving into the wind so the motor was working double time alot and the heat guage never went above the "o" on normal. fairly cool for that engine. the white smoke that is usually associated with the engine is burning oil is gone but the black smoke is still there b/c the injection pump was turned up 10% when it was overhauled but the power was increased and it fires right up when warm no need for glow plugs when its warm!!!!

very wonderful product!!! we will keep on buying it I might try to talk my dad into buying the fuel treatment too

We use Lucas Heavy Duty Oil Stabilizer in our dragster as an assembly lube and also as an additive to our regular engine oil. On more than one occasion it has saved us from replacing our rotating assembly. I went an entire pass without oil pressure and upon teardown we found that the Lucas had saved our crank and rods. I tell everyone I know to use this in their racing engines for extra protection and they will be glad they did!

On another note, just yesterday I lost the oil pressure in our old Ford pickup on the way back from Denver. This engine has well over 200,000 miles on it and is pretty weak. We put new oil in the crankcase along with 1/2 gal of Lucas oil stabilizer and drove it home from the truck stop. Thank you for a great product.

A couple weeks ago on my way home from work while I was climbing a mile and a half hill, I noticed the heat gauge telling me that the "buggy" was getting a little warm. at about the 3/4 of the way up the hill the gauge was also at 3/4 of the way up too. Well I figured i'd get over the top and let her cool down a bit by coasting down the backside into town. needless to say she was steamed up pretty good. I nursed her to a convience store at the bottom of the hill. After getting some water in her, and when most of the steam subsided, I could see a 4 inch split in the bottom radiator hose. I got some more water in her to help cool it down a bit, all the while realizing its not going to hold spit. I know I should have called a tow truck then and there but I didn't, I figured I'd "nurse" her home. The truck was starting to "clank" pretty good by now,so I stopped about every quarter mile to put water in.

I made it home and towed her to the repair shop for the hose and a new thermostat.

When I got the truck back, she ran like a top, and to this day she doesn't show any signs of oil leakage due to a warped head, and of she doesn't over heat.

Not to bad for a truck with over 175 thou on the odometer, and never been cracked open since I've owned her, some 150 thousand miles ago.

All this I owe to the "religious" use of the heavy duty oil stabilizer from LUCAS every oil change.

This is the gods honest truth. an this is what sold me on Lucas products.A friend of mine bought a 1990 F150 that was in excellent shape appearance wise but the little 5 liter ford had a rod bearing hammering somthing awful. Sounded like a gorrilla in side with a sledge hammer that wanted out. So he changed the oil put 3 or 4 quarts of oil in the crank case started it up and still the rod was hammering. And then he poured in the quart of heavy duty oil stabilizer and i am not kidding you within 5 to 10 seconds the sound got quieter and quieter until it just stopped banging. He kept this truck for another year or so and used it to pull his racecar and trailer and never had a problem out of the truck again and this is the honest to god truth so now i use lucas products in everything i own...

My wife owned a 1987 Buck Century with 140k miles on it with an oil leak that would dump about a quart every 3 weeks. She forgot to keep up with the leakage and let the car get about 2 quarts low. We were driving along on the highway and I noticed the engine getting a loud knocking sound and the oil light was flickering on and off. A good friend had given me a bottle of Lucas HD Oil Stabilizer to try and it sat in the trunk for 2 months. When we arrived home I was fed up with this car and put the Heavy Duty Oil Stabalizer into the engine. I Started up the car and within 2 minutes ALL engine knocks were gone, the engine shake completely disappeared, the oil light shut off and after a while the oil leak lessened. I've been a faithful Lucas Oil Advocate ever since. I just bought the Fuel Treatment for my 1997 Saturn SL and 2000 Toyota Tacoma and I can't wait to use it!!

At around 57,000 miles my engine started making a load tapping sound during start ups and would last until the engine would warm up. Fearing that I was in need of major internal engine work, I went to Autozone to see if they had any recommendations. The manager told me that everyone at the store uses Lucas Heavy Duty Oil Stabilizer on their vehicles and that it is known to reduce knocking and tapping sounds in engines. I changed the oil and added the product. Lucas Oil did not reduce the tapping sound, it completely ELIMINATED the noise. It saved me an expensive bill from the mechanic and I will now add it every 3000. I highly recommend this product to anyone.

i have been using your oil stabilizer for over 7yrs now in all my cars and lawn equipment. My camero has over 228k miles on it and it still runs like it only has 100k miles. It does not smoke or make any high milage engine noise's that you would be hearing by now with all those miles but it does not make any noise's what so ever. It also has all the horse power that it had when i first bought it 10yrs ago. I believe,no i know it is your product that is making my engine perform so well and running so good. My friends can not believe how good my car runs with all those miles. I will be writing back when i hit 300k miles and i'm sure it is going to go much further than that. Thanks alot for such a great product. Keep up the good work!

we began using lucas oil stabilizer four years ago and have found our high hour tractors and combines have reduced oil consumption and blow-by. Even used oil which we use to lubricate roller chain on machinery is better than commercial chain lube products becuase it sticks to the chain and heat won't break it down. The stuff makes good oil great. we believe lucas oil stabilizer extends the engine life of our tractors and combines.

Six years ago I aquired an '88 Dodge Dakota. The motor had nearly 300K miles on it and was knocking on cylinder number four. After rolling in a new set of bearings, lightly sanding the rod and main caps and adding pieces of .002" and or .003" brass shim-stock under the bearing caps the bearing clearances were back within specs. After driving the truck for two weeks the oil pressure at highway speeds had again dropped below 20 psi. I was sure that motor would not last another month. Just for the sake of trying I changed the oil and adder a quart of Lucas Heavy Duty Oil Stabilizer. The benefits were immediately noticed. Cold idle oil pressure was over 85psi, hot idle pressure was over 45psi and pressure at highway speed was between 55psi and 65 psi. This truck is not driven a lot but over the last six years I have put another 40K miles on this motor changing the oil every 3K miles and adding a quart of Lucas at every oil change. The motor still has the same oil pressure as when I first started using Lucas. As the owner of an automotive repair shop I now purchase Lucas by the case in gallon jugs and recommend it to all of my customers as well as use it in every vehicle I own. I use it in my 2002 Harley Davidson, 1997 Dodge Caravan with 266K miles, 1980 Dodge Power Wagon, 1996 Ram 1500, 1998 Dodge Durango, 2001 Honda Recon and all my kids dirtbikes and go carts. Anyone who cares about their vehicles would be wise to use Lucas products.

I am amazed at how quiet the engine in my wrangler is now that I used the oil stabilizer. It starts better and runs like new and as smooth as a sewing machine. Lucas Rocks!
